I just found the 1811 Elbing census online at the Mennonite Library and Archives (Bethel College, North Newton, Kans.) web site. They were scanned by Glenn Penner. Previously I had ordered LDS film #1344433, where it is also found. But the digital images at the MLA web site are better quality; and most importantly for a Mennonite, they are FREE!
Here is the page with my 5-greats-grandfather Gerhard Fast #660202 (1739-1828) at age 72 in Neustaedterwald. (I think the age of 75 that is given is wrong.)
NB: The MLA web site calls it the 1812 census - it was taken at the end of 1811 for the 1812 year.
